Seismic performance of these structures has been tested by the Kumaun earthquake of and Garhwal earthquake ofthat are considered to be highly dam- aging. The stones between the logs are mostly assembled without any grout or mortar thus enabling a certain level of flexibility and allowing lateral deflections of the building without damage effects.
